Convert the equation to Standard Form.

y=2(x+1)^(2)-4

Answers

Answer 1

Answer:

y = 2x^2 + 4x - 2  

Step-by-step explanation:

y=2(x+1)^(2)-4 is in vertex form.  We want the same equation in standard form, which looks like y = ax^2 + bx + c.

Perform the indicated multiplication (squaring of x + 1):

y = 2(x^2 + 2x + 1) - 4, or

y = 2x^2 + 4x + 2 - 4, or

y = 2x^2 + 4x - 2                   This is in the standard form of a quadatic.

Answer:

y=3/4x +7

Step-by-step explanation:

The equation for slope-intercept is y=mx+b, where m is the slope and b is the intercept.

To find b, we can plug in the x,y, and given slope.

[tex]4 = \frac{3}{4} ( - 4) + b \\ 4 = - 3 + b \\ b = 7[/tex]

so now we can write b and m in the original equation.

which gives us, y =3/4x +7

As per the question ;

Some measures i.e., 90 centimeters, 40 meters, 30 kilometers, 10 meters, 40 millimeters are given.

Let's check which is the longest by converting them all in same units say centimeters.

So ;

a) 90 centimeters

= 90 centimeters

b) 40 meters

= 40 × 100 centimeters

= 4000 centimeters

c) 30 kilometers

= 30 × 1000 meters

= 30000 × 100 centimeters

= 3000000 centimeters

d) 10 meters

= 10 × 100

= 1000 centimeters

e) 40 millimeters

=  40 / 10 centimeters

= 4 centimeters

So ; the longest is 30 kilometers.

Thus , the longest measure from the given measures is 30 kilometers.
